RAILWAY-TRACK CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed January 10, 1910. Serial No. 537,134.

To all whom it may concern:

-Be it known that I, JOSEPH W'. Brown, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Railway-TrackGonstruction, of which the following is a specification.

My invention relates to the improvement of railway track constructionand has particular relation to the construction of tracks for use inmines and similar places where it is desirable that a track may beconstructed rapidly and in an inexpensive manner.

The objects of my invention are to provide a comparatively simple trackconstruction and to embody therein improved means for producing adurable and effective connection between the ties and track rails; to soconstruct my improved track as to admit of the parts thereof beingreadily separated when desired and to admit of the use of sections ofordinary track rails as ties. These objects I accomplish in the mannerillustrated in the accompanying drawing, in which Figure 1 is atransverse section of a railway track having my improved construction,Fig. 2 is an enlarged vertical section on line w-m of Fig. 1, with thetrack rail removed, Fig. 3 is a view in elevation of one of the lockingpins which I employ in the manner hereinafter described, and, Fig. 4 isa detail view in perspective of the end portion of one of the ties.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention, I employ transverse ties l which arepreferably formed of track rails of the usual T-form. In preparing eachof these tie members for use as supports for track rails, I split theend portion of each -of the heads or tread members 1 of the tie railhorizontally and bend the upper member l thus formed upward and inwardto the hook form shown more clearly in Fig. 4 of the drawing. At a pointa suitable distance on the inner side of each of the hook members 1 andin the center of the width of the tie, I form a vertical pin receivingopening 2 which is continued downward into the web 1 of the tie rail inthe form of a slotted opening 2. As indicated at 2", I decrease thethickness of that portion of the web which forms the lower end of theopening-2 by cutting away or beveling the opposing faces of the web.

4 represent the track rails which are of the usual T-form in crosssection. These rail sections are laid in the usual manner transverselyupon the upper sides of the ties, each of the rails being so seated uponthe tie as to cause its outer base flange 4 to extend beneath theinturned hook members l of the ties. In order to further lock the trackrail in its position on the tie and in engagement with the hook member1*, I employ a locking pin 5 which as shown in the drawing, is formed inits upper and larger end with a spike head or projection 5 The lower andslightly tapering portion of the locking pin is split centrally from itslower end upward to a point near the center of the length of the pin,this split being indicated at 5*. The mouth of the split 5 is enlargedas shown, by beveling the adjoining surfaces of the lower end of the pinon opposite sides of the split or recess. The rail having been placed asheretofore described upon the tie and in engagement with the hook member1 one of the pins 5 is driven downward through the opening 2, with theresult that when the flaring mouth portion of the split or recess 5comes into contact with the comparatively thin portion of the web whichis at the bottom of the slot 2*, those portions of the pin which I haveindicated at 5 and which are on opposite sides of the split or recess5*, spread outward away from each other and on opposite sides of thelower portion of the tie web 1 after the manner of the spreading of themembers of an ordinary cotter pin. It will be understood that the pin isthus driven downward until its inturned head 5- is in engagement withthe upper side of that base flange of the track rail which is oppositethe flange 4.

By this operation, it will readily be understood that the track rail isheld in firm engagement with the tie, said rail being secured upon oneside by the hook members 1 of the tie and upon the opposite side by theheads of the locking pins 5. It will also be observed that the spreadingof the locking pin in its downard movement will serve to obviate anytendency of said pin working loose and moving upward in the opening 2.

It will readily be understood that the operation of constructing a trackby the means described, will be comparatively simple and inexpensive andthat such construction may be carried on without the aid of skilledlabor and by the use of ordinary track rail sections for both the tiesand track rails. It is also obvious that a track constructed asdescribed, will be exceedingly rigid, thus preventing spreading of therails and insuring the retention of the proper gage. It will also benoted that the use of bolts or nuts or similar fastening devices isentirely obviated.

From the foregoing description, it will be seen that simple andeflicient means are herein provided for accomplishing the objects of theinvention, but while the elements shown and described are well adaptedto serve the purposes for which they are intended, it is to beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the ap pended claim.

\Vhat I claim, is

In a railway track construction, the combination with a tie, formed of asection of track rail, the tread portion of said rail be inghorizontally split longitudinally for a short distance from each endthereof, said split portions being turned back to form hoop portions,openings formed vertically through the said tread portion, said openingsbeing longitudinally spaced a suitable distance from said hoop portions,that portion of the web of the rail at the base of each of said openingsbeing beveled, and split spikes adapted to pass through the said treadportion and to have their lower portions spread by contact with saidbeveled portions of the web, substantially as shown and described.

In testimony whereof I atlix my signature in presence of two witnesses.
